Reynolds Number 4
Reynolds Number 4 : A dimensionless number, Re, that occurs in the theory of fluid dynamics. The diameter, velocity, density, and viscosity (consistent units) for a fluid flowing through a cylindrical conductor are related as follows: Re = (diameter) (velocity) (density) (viscosity) or = DVp/u+ The number is important in fluid hydraulics calculations for determining the type of fluid flow, i.e., whether laminar or turbulent. The transitional range occurs approximately from 2,000 to 3,000; below 2,000 the flow is laminar, above 3,000 the flow is turbulent. (Bul D11)
